Abstract
In this paper, we examine the potential for using phase change material (PCM) as a thermal storage medium for improving the efficiency as well as enabling grid-responsive control of heat pump (HP) systems. Previous research in PCM integration in buildings has primarily been focused on integration with building envelopes. An objective of our research is to design a novel and practical PCM integration with existing HP systems. High-fidelity models for building, HP and PCM are developed to facilitate the model-based predictive control (MPC) design. To optimize the operation of HP and PCM, we introduce an optimization problem considering various constraints for both comfort and hardware constraints. We include experimental results in which a house fleet are optimized to minimize their power consumption or electricity cost. We numerically demonstrate the designs potential for reducing power consumption or electricity cost by 13% or 19%, respectively.
